their short ovate figure assist materially in characterizing the 

 species, agreeing most with those of .S. D ic kso nia na, irom 

 which the leaves of the present widely differ in form and silkiness. 

 Nevertheless, when the plant is cut down, the strong radical 

 shoots produce much broader, and partially elliptical leaves, 

 approaching to the universal shape of Dkksoniana, but are still 

 silky when young. Cultivation from seed, if possible, could 

 alone determine whether the plants vary into each other. We 

 know nothing of the h^xv&njlowers. The catkin in Dr. Wahlen- 

 berg's t. 16./. 2, i.s twice the length of our Arbuscukif and much 

 more lax, nor do the leaves agree.

Leaves elliptic-oblong, obscurely toothed, smooth ; livid 

 beneath. Stipulas none. Germen nearly cylindrical, 

 downy ; its stalk twice as long as the scale. Stigmas 

 nearly sessile.

Shrub 



Very smooth in almost every part, about a foot high, the young 

 branches spreading widely, and partly recumbent, with a yellow- 

 ish bark, which in its earliest state is a little downy, with curved 

 hairs. Leaves three quarters of an inch long, elliptical, slightly 

 dilated upwards, equally contracted at both ends, but not acute ; 

 distinctly, but not deeply, serrated or toothed ; the smallest veins 

 reticulated at right angles ; the upper side green and shining 5 

 under, as W'ahlenberg observes, livid rather than glaucous. 

 Footstalks short and stout. Stipulas never seen by the eminent 

 botanist last named, in any state or supposed variety, of the 

 plant. Catkins, according to him, lax, on short stalks, with I 

 or 2jloral leaves ; their common receptacle finely downy, as well 

 as the stalks of the germens, which are twice the length of the 

 little, ovate, likewise downy, scales. Germen long and cylindri- 

 cal, more thickly downy. Stigmas idmost sessile. 



1 have seen onlv a branch or two with the leaves, communicated 

 by my friend Dr. Hooker, wliich altogether agrees with the 

 above description ; what regards the fiuctijication is borrowed 

 from Dr. Wahlenberg's work. I cannot refer this Willow to 

 any described species, nor \n nnv of the Liiunean specimens.
